Lenovo introduces a completely new device with the fourth generation of the ThinkPad P1, including a 16-inch display with 16:10 aspect ratio and updated hardware. The P1 G4 also gives a first glance at the upcoming ThinkPad X1 Extreme G4, which uses the same chassis.

Please retest the P1 with a second RAM module.
Thank you for the exhausting review!
Alright, so are you saying Lenovo are now ditching good keyboards, which were the only reason to buy Lenovo laptops in the first place? Hmm...

Yes, definitely. Many reviews have noted big improvements to CPU performance by adding a second RAM stick.
Also, repasting the CPU & GPU could possibly alleviate some of those thermal issues (which of course, shouldn't happen in the first place). I've seen that the thermal paste application can be quite sloppy. First sign would be uneven temps between CPU cores in high load scenarios.
"Mediocre cpu performance" yet it gets an award and a 89% !! This is being sold as a workstation but this is not workstation performance levels.
That vertical enter key is a hard no for me.

The layout is different depending on the locale, US versions will have the ANSI type with narrow enter key.
Oooh I've been waiting for this one for a while!
I'm disappointed in the CPU performance however and while I don't need the more powerful GPU I'd like to see the CPU performance with the vapor chamber (sounds like this will be reviewed in the next week or two which is great.
It would be good if mention can be made of a 90w or 100w USB-C charger compatibility with this more powerful config too :)
This getting ridiculous.
An Alienware with same CPU gets 14000 points in Cinebench R23 multi, while this one can only get 9300...
Basically these workstations are just for corporations to save their asses from legal issues: not our fault we bought a "professional" computer.
Thanks for the exhaustive :) (and not in the least exhausting) review.
Very detailed.
It seems to be that the Ryzen 5700U is the processor to get if you want good thermals and good battery life. For some reason x86 35-45W cpu's don't seem to do a lot more for a lot more (intel 11800h, ryzen 5800h) - not sure why. But even here, at the 45W TDP - which is likely where workstation CPU's end up, the Ryzen 5800h is ahead again. This is as much an issue with Intel's poor performance under thermal envelope, as it is of Lenovo not doing a good job allocating thermals appropriately between cpu/gpu. The M1X will likely eat Intel's lunch when it is announced.
Bought one of these last week. Installed windows 11, used it for around 4 hours and now it refuses to power on. :(
Apart from that the screen was great, sound was pretty good too.
Hey guys, great in depth review as always! Could you please re-test CPU performance with another ram stick running in dual channel ?
Hi, I will test with dual-channel later, but I don't think this will impact the TDP behavior, since it is regulated by the cooling performance.
@ksh
The problem is not AMD or Intel. It is the energy limitation that some chassis manufacturers put into their laptops.
An Intel i7-11800 can do 14000 in Cinebench R23 multi
A Ryzen 7 5800H can do 13200 in Cinebench R23 multi
But just a number of systems can do it : Lenovo Legion, some Alienware, some MSI, some Razer. Probably others but you need to check by model the power available for the CPU and also the GPU.
Just Josh channel on YT has a good explainer on this. The P1/X1E CPU alone draws 57 W on "combined sustained load" - much lower than most other laptops where the Intel 11th Gen CPU usually draws between constant 70-100 W when both CPU/GPU are utilized.

Thank you for that link Dorby - I note he has a vapour chamber model and I'm surprised that the CPU power usage and in turn the performance isn't as high as some other models as I would have thought the vapor chamber would allow the CPU to use a lot of power when only it is under load and not the GPU.
Interesting his one still charged off 100w USB-C, I was wondering if that might not be a thing with the bigger graphics cards. (as I mentioned in my earlier comment)
Just one question, was a 65w charger tried when the laptop was powered off? Or does that not work at all.
CAD might need GPU for rendering.
One of recent developments in Architecture rendering is using Unreal engine. Also now in use for product design. That implies at least a 3060 preferably a 3070/3080.
A 65W charger does not charge the battery, even when the device is turned off.
The BMW27 Blender test done for CPU should also be done for the GPU/Optix.
Then compare it to a RTX3060 ... it will be clear that this card is inferior.
Since HP zbook studio g8 also only has vapor chamber on higher GPU configuration.
Will Zbook studio g8 has the same issue as well?
Could you test the HP zbook studio g8(without vapor chamber version) to see if it has the same issue?

Even HP's consumer line 1300$ Envy 15 comes with vapor-chamber by default on its RTX 3050 base model SKU.
I've used the ZBook Studio laptop and while its surface temperatures aren't ideal, the CPU performance you get on the HP is much better than on the X1 Extreme.
Edit: My bad, looks like T1000 has no vapor chamber cooling
Dear dorby
you are inccorect:
For the latest version of Zbook studio and fury (g8)
You can found the floowing :"he HP custom vapor chamber (Z VaporForce) is only available on configurations with NVIDIA RTXTM A3000 Laptop GPU or GeForce RTXTM 3060 GPU and higher GFX."

This is incorrect. HP ZBook Studio since the original uses vapor-chamber cooling on all configurations including Quadro.
Even HP's consumer line 1300$ Envy 15 comes with vapor-chamber by default on its RTX 3050 base model SKU.
I've used the ZBook Studio laptop and while its surface temperatures aren't ideal, the performance you get on the HP is much better than on the X1 Extreme/P1.
Hey,
thanks for review!
I didn't get from the review comparison between P1 and X1extreme CPU on dual-channel... Is it bad for both of them or does X1extreme have better CPU performance?
If CPU is lower than expected for i7-11th, can you then recommend this laptop for programming/multi-threading?
Thanks!
Is the second SSD slot really a 2280 slot ?
From looking at the image it looks like a 2242 might fit there, but not a 2280 ? Which will be very sad, because I preemptively ordered a 2280 nvme ssd. :/
Hi, and thx for the review. I am curios to know, how can the same panel have such variation in contrast B160QAN02.M in P16 is 998, and B160QAN02.M in P1 G4 is almost 40% higher. Can panel variation be so high across panels?
